scion-shell: A simple shell environment for the SCION SCXML interpreter. It accepts SCXML events via stdin, and thus can be used to integrate SCXML with Unix shell programming. It integrates scxml-viz, so can also allow graphical simulation of SCXML models.

scion-web-simulation-environment: A simple proof-of-concept web sandbox environment for developing SCXML. Code can be entered on the left, and visualized on the right. Furthermore, SCION is integrated, so code can be simulated and graphically animated. A demo can be found here: http://goo.gl/wG5cq
